H EATING-STOVE.

` SPECIFICATION forming part of Letters Patent No. 254,783, dated March *7, 1882.

Application filed January 7, 1882. (No model.)

To all whom it may `concern Be it known that I, JOHN SrRAszEn, a citizen ofthe United States, resident of Manchester, in the county of St. Louis and State of Missouri, have invented a new and valuable Improvement in Stoves; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation ofthe same, reference being had to the 1o annexed drawings, making a part of this specification, and tothe letters and figures of reference marked thereon. y

Figure l ofthe drawings is a representation of longitudinal section of my invention. Fig. i5 2 is a cross-section, and Figs. 3 and 4 are detail perspective views.

This invention has relation to hot-air stoves; and it consists in the construction `and novel arrangement of the horizontal hot-air flue vin 2o the upper part of the stove, the hollow plate at the back of the stove forming an 11p-draft line for cold air, and communicating by an opening at the back of the stove with the horizontal flue, the rear and front flange-bearings 2 5 for the latter flue. and the front register-door haviuga bottom hinge and stop-shoulder, all as hereinafter set forth, and especially pointed out in the claims appended.

In the accompanying drawings, the letterA 3o designates the wall ot' an ordinary box-stove having myinvention applied thereto.

B B indicate openings made in the upper part ot the front and rear walls of the stove, said openin gs being preferably of circular form and provided with annular interior flanges or rim-bearin gs o, for the ends ot' the horizon tal flue, D, into which they are inserted. The front flange or rim-bearing c is designed to be formed on a collar, E, having an exterior or 4o face flange, f, provided with holes y, through which the fastening-bolts It are passed. This collar is therefore removableas is also the cylindrical flue D, which is usually made of sheet-iron and can be easily replaced when too 4. 5 much burned for service.Y

At the back of the stove, in rear of the rear opening, B', is the tip-draft flue-plate F, which extends to the bottom of the stove and is provided with an inlet-opening, 7c, at its lower end. This line receives cold air from the lower 5o part of the room and guides it into the horizontal ilue D through the opening B. In this flue it is heated and emitted through the front openin g, B, or through the register-open-` ings Z,.in the door G thereof. This door is hinged by its lower horizontal border to the stove-wall below the opening B, and it is provided with a bearing-shoulder, m, at right angles with its face and in front of the hinge, so that when it is dropped from the opening on 6o its hinge it will be stopped in the horizontal position, and will form a very convenient shelf or ledge on which articles may be placed to receive the warm air which is emitted from the opening B.

It will be apparent that in this construction the horizontal due D is the main heater for the air passing through the stove, and that its action is greatest in the rear part, where it is subject to the greatest heat, the front portion 7o of the stove being comparatively cool. This tlue therefore draws the air rapidly up through the vertical rear flue, F, and discharges it warmed through the front opening.

By means ofthe register in the door G the discharge of hot air maybe regulated, or it may be shut off entirely. y

The devices described hereinbefore can be easily applied tolarger stoves or heating-furnaces. 8o

A horizontal hot-air ue in the upper portion of the stove communicating with an updraft flue in the rear portion of the stove and a register-door in the front of the hot-air ue is not new, and is not broadly claimed hereinafter.

Having described this invention, what I claim and desire to secure by Letters Patent,

l. ln a heating stove or furnace, the wall- 9o openings B B' in the upper portion, the updraft-flue plate extending from the rear opening, B', to the bottom of the stove, the rimbearings c, the removable front collar, E, and

the removable horizontal hot-air flue D, hav- In testimonythat I claim the above I have 1o ing its ends seated on said rim-bearing, subhereunto subscribed my name in the presence lstanaiaily as specified. of two witnesses.
